What homeowners usually notice
- The outside outlet is dead after rain or a storm.
- Holiday lights, a pressure washer or yard tools will not run.
- The GFCI on the outlet trips every time it rains or every time you plug in a tool.
- The cover is missing or cracked, or the outlet shows rust or green corrosion.
What to do right now
- Press RESET on the outdoor outlet if it has buttons.
- Look for a GFCI inside, in the garage, bathrooms, kitchen or basement, and reset it.
- Check the panel for a tripped breaker or GFCI breaker and reset it once.
- If the outlet or cover is wet, leave it off until everything has dried out.
Likely causes
Tripped GFCI elsewhere
Outdoor outlets are often protected by a GFCI inside the garage or a bathroom. When that GFCI trips, the outside outlet goes dead with no clue where to look.
Moisture in the box
Rain, sprinklers and pressure washing can push water into an outlet without a proper cover, tripping the GFCI and corroding the contacts.
Wrong or damaged cover
Older flip covers only protect the outlet when nothing is plugged in. An in-use (bubble) cover keeps water out while cords are connected, which is what current code expects for outlets in wet locations.
Worn-out GFCI
GFCI outlets exposed to heat and weather wear out and may refuse to reset or trip constantly.
Faulty cord or tool
A damaged extension cord, string of lights or tool left in the rain can leak current and trip the GFCI as soon as it is plugged in.
Safe checks you can make
- Unplug everything from the outdoor outlet before resetting the GFCI.
- Note whether it trips only after rain, only with a certain tool, or all the time.
- Look at the cover, gasket and outlet face for cracks, rust or insects.
- Check whether the outlet is under a gutter, near sprinklers or low to the ground.
Leave outlet covers, switch plates and the panel cover in place. Noting what you see and hear is enough; testing inside boxes belongs to an electrician.
Is this something you can fix yourself?
Resetting the GFCI, finding a hidden one in the garage, and letting a rain-soaked outlet dry are all safe things to try. If it holds when nothing is plugged in but trips with one string of lights or one tool, the cord or tool is likely the problem, not the house. When the GFCI will not reset, the outlet is corroded, or it trips on its own in dry weather, the outlet or its wiring needs attention, and that involves opening a weather-exposed box, which should be done by a pro.
When professional help is the right call
- The GFCI will not reset, or trips immediately with nothing plugged in.
- Visible corrosion, rust, cracks or water in the box.
- The outlet feels warm or shows scorch marks.
- The outlet is missing a cover or has an old flip cover that lets water in.
Safety first. Do not handle a wet outdoor outlet, and do not plug anything into one standing in water. If you see sparking, smoke or melted plastic, turn off the breaker if it is safe to reach and call for help; if anything is burning, call 911. Outdoor electrical faults and water are a dangerous combination.
What an electrician typically checks
An electrician finds the GFCI protecting the outlet, tests it, and opens the outdoor box to check for water, corrosion and loose connections. They replace a worn GFCI with a weather-resistant one and install a proper in-use cover and gasket so the outlet stays dry with cords plugged in.
If the box is low, loose or in a spot that collects water, they may relocate it or add a new outlet, which falls under GFCI outlet repair and outdoor outlet installation. They can also check whether any other outdoor outlets on the home lack GFCI protection.
Keeping it from coming back
Keep an in-use cover closed on every outdoor outlet, and do not leave cords plugged in through heavy storms. Birmingham gets strong spring and fall storms and plenty of summer rain, so outdoor GFCIs see a lot of moisture; test them monthly with the TEST button. Use outdoor-rated cords and lights, and read why a GFCI keeps tripping if yours trips after every rain.
